| 摘 要： | 对到界边坡下采用螺旋钻机开采煤柱不同开采顺序引起的破坏过程进行了数值模拟。模拟结果再现了不同开挖顺序对煤柱破坏的影响,模拟结果表明:层间不同开采顺序对煤柱稳定性影响较大,而同一层内开挖顺序影响不明显;研究结果为优化煤柱设计和现场施工工艺提供了理论依据。

| Abstract: | The fracturing process induced by different excavation sequence under final highwall with auger mining was numerically simulated. The simulation results reproduced the effect of different excavation sequence on the fracture of coal pillar and indicated that different excavation sequence in different levels exerts great effect on the stability of coal pillars, but in the same level the effect of excavation sequence is not obvious. The study results provided theoretical basis for optimum design and excavation technology of coal pillar. |
